You can't eat moon cakes after they expire for three months. Moon cakes are traditional food for Mid-Autumn Festival, symbolizing reunion, auspiciousness and missing. There are many kinds and fillings. Usually, the shelf life of moon cakes is mainly affected by the stuffing and packaging of moon cakes. The shelf life is generally about 1-3 months, depending on the stuffing of the moon cake and the regulations of the merchants.

The reason why moon cakes on the market can be preserved for a long time is that preservatives are added when they are made, which can prolong the shelf life of moon cakes. However, the homemade moon cakes in life generally do not add preservatives, so the shelf life of homemade moon cakes is relatively short, which can only be stored for about 10 days, otherwise it will easily deteriorate and be harmful to human health after eating.
